Key Foods

The Nutrient Data Laboratory is responsible for developing authoritative nutrient databases that contain a wide range of food composition values of the nation's food supply. This requires updating and revising the USDA Nutrient Database for Standard Reference (SR) and developing various special interest databases. However, with over 7,000 food items in SR and a complete nutrient profile costing approximately $2,000 for one sample, analyzing every food item for every nutrient and meeting all user requirements is impossible. Consequently, priorities must be determined. Procedures using food consumption data and nutrient values for developing the Key Foods list are explained. Key Foods have been identified as those food items that contribute up to 75% of any one nutrient to the dietary intake of the US population.  These Key Foods will be used to set priorities for nutrient analyses under the National Food and Nutrient Analysis Program. The tables describe key foods based on Continuing Survey Of Food Intakes By Individuals (CSFII, 1989-) and WWEIA-NHANES (What We Eat In America - National Health and Nutrition Examination Survey 2001-) survey data.

营养数据实验室负责构建权威的营养数据库，其中包含国家食品供应中广泛的食物成分值。此任务要求对美国农业部营养标准参考数据库（SR）进行更新与修订，并开发多种特定兴趣数据库。然而，鉴于SR数据库中包含超过7000种食品项目，且一个完整的营养成分分析样本的成本约为2000美元，对每一种食品和营养成分进行全面分析以满足所有用户需求实属不易。因此，必须确定优先级。本文解释了利用食品消费数据和营养成分值来制定关键食品清单的程序。关键食品被定义为那些对美国家庭膳食摄入中某一特定营养成分贡献率高达75%的食品项目。这些关键食品将用于国家食品与营养分析计划中营养分析的优先级设定。表格基于个人食物摄入持续调查（CSFII，1989年及以后）和“我们在美国吃什么”——国家健康与营养检查调查（WWEIA-NHANES，2001年及以后）的数据，描述了关键食品。本数据集包含的资源如下：
